Largest motor of its type

A new blower station has been installed in a Chinese iron and steel factory. Three axial blowers now produce a maximum air volume of 10 000 Nm3/min at 0,65 MPa. The drive technology for this enormous blower has been provided by Siemens. The electric motors installed here are the largest of their type in China and ensure significant operational savings. The blower station is driven by three Simotics HV 60 MW high-voltage motors, the largest of their type in China. The motors were supplied by Siemens together with nine further synchronous motors, two Sinamics GL150 frequency converters with an output of 14,6 MW, and a medium-voltage switchgear set. The motors provide extremely efficient operation as they do not require an additional transmission.
